Magma

Chapter 6 Troubleshooting

Before discussing a troubleshooting methodology for locating the problem we will first introduce several indicators and
configuration switches that provide general and specific information for this process.

Status Indicators and configuration switches

Under normal operating conditions the status indicators are for internal Magma troubleshooting while the configuration
switches/jumpers should remain in their default state preset by Magma for best compatibility. However, should a
problem occur with the chassis (or a special mode of operation be solicited by the client) we included below
explanations as to what all these items are and how they should be treated:

Status Panel indicators

All LED's should be green at all times. An orange LED means a fault of the corresponding item listed in the picture above.

Chassis Signal Detect Indicators

This group of LEDs (D2, D6-D8) indicates the existence of PCIe traffic on the receiver side on the respective PCIe lanes. In
the example shown here, an active x8 link is identified by x1, x2, x4, and x8 LEDs being ON. During normal operation
signal detect LEDs and D14 (clock good) should be ON with the exception of D9 whose role is to indicate loss of signal
and logic failure.
